Overpasses and Walkways
Overpasses and Walkways
Selco manufactures overpasses to support the flow of pedestrian and vehicular traffic. These structures utilize techniques, such as replacing at-grade intersections with elevated structures to help reduce congestion.
Our overpasses comply with the Americans with Disabilities Act (ADA), with width, tread depth, and ramps built according to stringent accessibility standards.
One of our past projects is the Bayshore Overpass Pedestrian Bridge, where we incorporated weatherproof materials and corrosion-resistant coatings to enhance durability.

Platforms
Platforms
Selco Manufacturing designs and fabricates industrial platforms that provide safe, durable, and reliable access for various applications. Our platforms are built to withstand heavy loads and high-traffic environments, ensuring stability and longevity. Using high-strength materials such as stainless steel, aluminum, and galvanized steel, we customize each platform to meet specific project requirements while maintaining corrosion resistance and structural integrity.
Safety and compliance are integral to our platform designs. We ensure that all platforms meet OSHA, ADA, and other regulatory standards, incorporating features such as slip-resistant surfaces, handrails, and reinforced load-bearing structures. Whether used for machinery access, maintenance operations, or elevated workstations, our platforms enhance both efficiency and workplace safety.
We offer modular and prefabricated platform solutions to streamline installation and minimize on-site labor. These pre-assembled sections integrate seamlessly into existing facilities, providing a cost-effective and time-saving solution for industrial and commercial environments.

Catwalks
Catwalks
Selco’s catwalk systems provide safe and efficient elevated pathways for workers navigating complex industrial and infrastructure settings. Designed to improve accessibility and workflow, our catwalks are built with high-quality materials that ensure durability in both indoor and outdoor environments.
Our custom-fabricated catwalks are engineered to meet OSHA and other safety regulations, featuring slip-resistant surfaces, guardrails, and robust structural supports. Whether spanning equipment, production lines, or hazardous areas, our catwalks enhance mobility while maintaining worker safety.
We specialize in modular and prefabricated catwalk solutions, reducing installation time and ensuring a precise fit within existing facilities. Our designs accommodate various industry applications, including manufacturing plants, warehouses, transit systems, and infrastructure projects, providing reliable elevated access where it’s needed most.

Stairways, Walkways, and Catwalks
Stairways, Walkways, and Catwalks
Selco fabricates stairways, walkways, and catwalks engineered for efficiency and safety in demanding environments. Using grated surfaces provides exceptional traction and prevents moisture accumulation, complying with Occupational Safety and Health Administration (OSHA) standards.
Our stairway, walkway, and catwalk components can be hot-dip galvanized for superior rust resistance, making them an ideal solution for marine or outdoor applications prone to environmental wear. Catwalk, staircases, and platforms can be customized to integrate seamlessly into existing transit stations, industrial plants, or other structures, offering a cost-effective solution for personnel safety and maintenance access.
Miscellaneous Steel Fabrication
Selco Manufacturing has American Institute of Steel Construction (AISC) and American Welding Society (AWS) certifications, providing innovative custom steel manufacturing solutions for overhead catenary systems, highway structures, and marine components.
Our advanced fabrication capabilities are ideal for complex projects that require:
Railings and Handrails
Selco offers aesthetically pleasing, durable railings and handrails fabricated from aluminum, carbon steel, and stainless steel. These products meet stringent industry standards and are vital to walkway and bridge safety. For example, we fabricated over 1,300 feet of handrails and 6,000 feet of picket fencing for the Willis Avenue Bridge project.
Our fabricated railings provide long-lasting durability and functionality, even in highly corrosive environments. We comply with regulatory requirements for:
- Bridge railing heights
- Impact resistance
- Loads
- Materials
At Selco, our attention to detail ensures that our bridge trusses, canopy structures, and other components are highly functional and aesthetically pleasing.
Electrical and Power Distribution
- Cast Copper Connectors and Terminals for DC Power Distribution Systems
As a pioneer of DC traction power distribution systems, Selco supports industrial and transit applications with a comprehensive product line that includes:
DC power systems are vital elements of transit applications, offering high efficiency and torque for starting trains from a dead stop. Our stinger systems safely supply wayside power, allowing maintenance yards to provide temporary power to vehicles during repairs.
These solutions meet the National Electrical Manufacturers Association (NEMA) and International Electrotechnical Commission (IEC) standards, ensuring total reliability in mission-critical applications.
- NEMA-Rated Enclosures
Selco offers the following NEMA-rated enclosures designed to protect electrical systems from exposure to harsh environments:
These NEMA enclosures safeguard utility systems, DC switchboards, control panels, and other critical components. Our custom designs can accommodate features such as internal ventilation, reinforced mounting systems, and gasket seals to prevent overheating and comply with Underwriters Laboratories (UL) and National Fire Protection Association (NFPA) standards for electrical enclosures.
Specialty Fabrication
Specialty Transit Fiberglass Fabrication
The unique properties of fiberglass make it a good material for manufacturing durable, lightweight custom enclosures that house sensitive electronic systems exposed to corrosive chemicals. Properties of fiberglass enclosures include:
Fiberglass is best suited for applications that require sound absorption or radio frequency (RF) transparency, such as noise-dampening enclosures and communication panels.
At Selco, our fiberglass fabrication includes pencil boxes, blue light panels, and DC switchboards. These components meet industry specifications, including American Society for Testing and Materials (ASTM) standards for flammability and mechanical properties.
Transit-Specific Applications
Overhead Catenary Systems
Selco fabricates the steel components that support overhead catenary systems, ensuring reliable structural integrity for high-speed transit operations. Our precision-engineered support structures, including tensioning devices and dropper assemblies, maintain even tension distribution and durability, preventing wear or sagging during extreme weather.
Manufactured to precise tolerances, these components contribute to consistent system performance and longevity. Our steel fabrications comply with European (EN) standards for railway applications, making them a dependable solution for today’s rail systems.
Stinger Systems
Stinger systems supply temporary power to transit vehicles during repair and maintenance processes. Selco offers two primary configurations, which include:
Each Selco system includes DC switchboards, stinger cables, and control enclosures, which we design and assemble in our ISO-certified facility. Our stinger systems are compatible with various rail vehicles, enhance maintenance efficiency, and reduce downtime.
